I have not been able to find a current thread on the techniques of successful capturing of birds in flight. My first attempt at the Carolina Raptor Center was shooting at 1/1250 sec, AF-C 9 point. 70-200mm f/2.8 VRII Nikkor. D4. 9 FPS. The birds were coming toward me at a 30° angle, and there was no choice as to the angle as we were given only small lee-way as to position.
After not being able obtain focus on the very fast moving birds with a few exceptions, I finally changed to the 3-D focus, but unfortunately this was the end of the session. It could be the problem was the distance the birds were…the release from about thirty feet, flying by as close as 5 feet, thus creating only a second or two for the exposures to be captured.
So, if there are any folks who wish to share their experience on capturing BIF…. I am all ears. ^:)^
